... at Reynolds numbers ranging from approximately 300,000 to 900,000 in a rectangular channel with an aspect ratio (width/height) of 1.29. The rib height is 3% of the channel hydraulic diameter, while the rib spacing to rib height ratio is fixed at 10. Heat transfer measurements are performed on the flat surface...

... to obtain a detailed distribution of heat transfer on the internal tip surface. In this study, the leading and trailing surfaces of the channel wall were either smooth or roughened with 45 deg angled ribs. The Reynolds number inside the pressurized cooling channel ranged from 10,000 to 30,000...

... study has been carried out here for different combinations of constrictors like ribs or protrusions along with cavities on the sidewalls of a microchannel (MC). A facing pair of cavities with circular arc sections, together called a fan-shaped cavity (FC), has been considered. Each in the facing pair...
